T0 at whont it may concern:

Be it known that I, SAMUEL B. PARMELEE, a citizen of the United States,and a resident of Saratoga Springs, county of Saratoga and State of NewYork, have inventedcertain new and useful Improvements in IndexedFolders or Pamphlets,of which the following is a specification,reference being had to the accompanying drawings, forming a partthereof, in which similar letters of reference indicate correspondingparts.

My invention relates to an improved form of indexed folder or pamphletwherein I provide a folder or book which is formed of one sheet ofmaterial-so folded, arranged, and out as to make every two or moresuccessive pages longer or wider than the two or more preceding pages.

The object of my device is to provide a.

folder or book which may be very easily made up at small cost and at thesame time pro vide pages which are suitably indexed; and a furtherobject of my invention is to provide a folder or book which may beprinted on one or both sides before being folded.

My invention will be fully described in the following specification andis illustrated in the accompanying drawings, in which- Figure 1 is aview of the sheet forming the folder or book spread out, and shows thelines of the folds by means of dotted and dash lines. Fig. 2 is a viewshowing a sheet partly folded. Fig. 3 is a view showing the sheetentirely folded and inolosed in a cover ready for fastening. Fig. 4 isan open View of the folder with the end partially broken away, showingthe successivelayers of pages; and Fig. 5 shows a view of the folder inits complete form.

A designates a sheet of paper or other suitable material printed on oneorboth sides with suitable reading matter or the like, and is partiallycut away at the center, as at a. This sheet is first folded along theline a. It is then folded backward along the line a and again along theline a when it assumes the position shown in Fig. 3.

By using a single sheet of the material two leaves of the same size Bare obtained, two leaves B, slightly smaller than B, are folded againstthe said leaves, and two leaves B still smaller, are folded against theleaves B,

and, lastly, two leaves B fold against the leaves B and all are inclosedwithin a cover 0, which has its front leaf slightly smaller than thefolded leaf B and its last leaf the same length as the leaf B orslightly larger, if desired. The leaves after being formed by the foldsas indicated are securely fastened by means of the fastening c, and thebook is ready for use. It is intended that this book or folder bedistributed in the condition just described, and shown in Fig. 5. Theupper edges formed by the fold a and the edges formed by the fold a areintended to be cut in the ordinary way by means of a paper-cutter afterbeing received by the user; but'it is obvious that by the use ofsuitable machinery the folder may be out before being distributed.

The essential feature of this invention is the arrangement of the pagesof the folder to form the stepped margins 17, I), W, and b upon whichmay be printed in full the subject to which the reading matter on thatpage appertains, thereby making it an easy matter for the user to findthe page of any particular subject contained in the folder.

Heretofore books and pamphlets have been made havingindexes in which theedges of the pages are only partly cut away and were so arranged thatvery little printed matter could be placed upon them; but none haveshown an index formed by cutting away the edge of a page along itsentire length, thereby making the pages successively smaller andadmitting of considerable printed matter on the indexes thus formed.

In the drawings I have shown a folder made up of a single sheet, therebygiving two leaves or four pages to each index; but it is obvious thattwo or more sheets may be used, in which case each index will have twiceas many sheets or four times as many pages as the number of sheetsoriginally used. This principle may be employed to index magazines anddaily or weekly papers.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is v A new article of manufacture comprisingan improved folder or book formed of one sheet of material, having twocut-away portions adjacent to the folding-line a as at a and foldedalong the center line a and again along the line a? at right angles tothe first fold and at a slightly-greater distance from the outer edge ofthe leaves 13 than from the 5 outer edge of the leaves B and thirdlyalong the line a parallel to the'line a? of the second fold and at adistance from the center on the side away from the last fold, so as toform leaves successively smaller, producing therero by stepped margins,along the edges of the said leaves, adapted to be used as indexes,substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 7th day of June, 15 1900.

SAMUEL B. PARMELEE.
